Particle cloud not showing in my rviz ROSJECT

Course Support ROS2 Navigation

When I set my 2D Pose Estimate, the particles do not seem to show up. Below shows the config of my rviz2:

Help would be appreciated. I have also not forgotten to run these 2 commands before opening rviz2:

source ~/ros2_ws/install/setup.bash
source /home/simulations/ros2_sims_ws/install/setup.bash

Nevermind I got it to work. Forgot to set reliability policy to best effort for my PoseArray topic.

Thanks! For me, the particles didn’t show up until I:

  1. set my 2D pose estimate (this made the PoseWithCovariance display)
  2. moved the robot with ros2 run teleop_twist_keyboard teleop_twist_keyboard
